To all'whom it may concern: y

B e it known that I, J AMES' CAVANAGH, Jr., a citizenv of the United States, residing at- Boston, in the county of Suffolk and lState,

of Massachusetts, `have invented certain new and useful Improvements in Machines for Operating on Insoles; 'and I do hereby de# clare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled inthe art to which it appertains to make and use the same.D

rllhe prsent invention relates to machines for operating on inso-les and more particularly to a machine adapted tO form trans verse slits extending part way only through the thickness .of an insole at the points where the stitch receiving rib .begins and ends.

In the manufacture of insoles and. particularlyof insoles for welted shoes, a stitch receivingrib is formed on o-ne surface of the sole extending throughout that portion of the" sole which is to receive the inseam by4 which the insole is attached to the Welt and upper of the shoe. This stitch receiving rib is formed by slitting the edge of the insole and turning up a portion thereof to form .sole by removing a skiving therefrom.` On

account of the difliculty of entering the rib forming knife or knives into the insole and removing them therefrom, and also on account of the fact that there is nothing on the l surface of the insole to guide the operator in determining' the points at which the stitch receiving rib should begin and end, the rib forming knife or knives are usually entered into and removed from the sole upon the heel portion of the sole, so that the stitch receiving rib extends on to the portion OI the sole which forms the heel seat. This not. only weakens the heel seat but in the case of'avsole provided with an upturned lip cutfrom the edge ofthe sole, necessitates slitting the lip at a subsequentooperation at the points where the inseam should begin and end, and also necessitates turningback the lip upon the heel seat. l

The principal' Object of thev present invention is to provide an improved machine by which transverse cuts can be formed in an insole at predetermined distances from the heel end of the sole at the points Where the stitch receiving rib .begins and, ,ends, said slits extending part way only through the `thickness of the sole and preferably being oblique to the surface of the sole and eX- tending towardv the toe end of the sole, as thereby no abrupt angle is formed at the junction ofthe heel and shank portion of the sole, and a better surface is provided to receivethe crimped in edge of the counter where the shoe is lasted;

.A machine embodying the present iiivention is 'intended primarily for operation upon an insole before the sole is subjected to the action of the rib forming knife O`r knives of an insole channeling or edge splitting machine, the slits made by the machine r serving not only to niark the points at which the stitch receiving rib is tO Abegin and end' but also serving as an entrance and an exit for the rib forming knife or knives. In

its broader aspects, however, the invention contemplates the provision of a machine is placed upon the sheetgof reinforcing material with its unribbed surface uppermost,

iandsince there is no mark on the surface of the insole `.to indicate the points at which reinforcing material is not uniformly applied to different soles, and often the relinforcir'igmaterial extends te a considerable distance beyond the ends of the stitch receivy 4ing rib andupon the'heel seat of the sole.

To enable the reinforcing material to be applied properly and in a uniform manner to insoles," a feature ofthe present inventioncontemplates the provision, in amachine forV operating yupon insoles, ofl means -for marking the unribbed surface of the Sole ati a predetermined point with: relation lthe stitch receiving rib begins and ends, the

Ios

x machine and also tothe operator who cuts y 'slitting knives for operation on soles o diftothe ends of the stitch receivin A `rib so that'I these marks'may serve as a gui e when-thefoff or butts the ends of the welt.

In addition to thenfe'atures of 1nvent1on above referred to themachi'ne .,hereinatter described .as jembodym'g the preferred form i ofthe present invention also' embodies certain novel 'constructions and arrangements "of parts, such for instance as aA novel presser foot for'holdingthework and means for operating it,` means'lfor regulating the depth of the slits made bfy'jtheknlves y 1n s oles of different thickness, means for adJustmg the ferent sizes", for determinin the posi-f tion of soles of diiierent sizes ywit relation j to theknivc's, .11.18.3115 for 'sup ortlng the. sole whereb'yfthe vslits-are forme adireetion inclinedtthe surfa'iieoth sole,'and means illustratedinFig. 7 to 'mark-thesize num for., markingmthdfsize ni1m upon one` surface thereof.

er the ysole described, and to enable the depth extends and a sprin aie indicated at 1 and each knife is mounted in a-separatev block 2 and adjustably secured therein by means of a bolt 3 passin throu h a slot in the knife andv through t e' bloc the provision of the slot inthe knife permitting-the knife to be adjusted longitudinally. The blocks 2 are mountedupon the under side of a reciprocating slide 4 and are secured to the slide by the bolts 3 whichextend .u wardly through transverse slotsin the sli e and screw into L-shaped blocks 5 on the upper'side of the cross head. By this construction the .bolts 3 act to secure the slitting v@knives I inthe blocks 2 and also' act tol clamp the blocks 2 and 5 to the.

slide. Theprovision of the transverse slots in the slide 4 ermits the blocks 2 and 5 and Athe slitting 'ves to be adjusted trans,- versely toward 'andfrom each other. to adapt the'knives for operation vupon soles of different sizes. ,T o', enable the knives to be adjusted accurately and simultaneouslythe upwardly extending portions vof the blocks s em'eawith' .an adjusting screw '.6 provi withright. and left threads and havin the screw can be convenienti rotated., The

.screw isheld fromlongitu inal movement by lugs projecting u wardly fromtheslide Y 4 .u on each side oft e disk.

he slitting 'knives are .caused to slit the msole,` placed in the machine, by mechanism anism, as illustrated, consists of a.. crank pin 8 mountedin a disk9 lon the ldriving shaft..

10 of the machine, and 'a link 11 connecting the crankpin and the slide. The supportl for the'insole'is stationary dur-in' the operatlon of the machine, as will be ereinaifter of the cuts made in soles of different thicknesses to be regulated, a yieldin connection is provided 1n the mechanism or actuating. the slide 4,

so: that the slide can be advanced differents distances for diderent thicknesses of' soles. l

As illustrated this yielding connection is 'provided between the link 11 and 'fthecrank pin 8, .andto' this end the vlinkti, is. provided with` a slot through which the `cran;k pin is 'provided in thelin which bears against the crank pin and tends to move theflink so; that he crank pin is in engagement, with the outer end 'of the slot.

cross head and theparts .of its actuating secured thereto. between the blocks a knurle disk 74 by which For. convenience?. 1n assembhng the pax-mand to -enab1e the 'which -reciprocates the slide 4. This mech-,-

mechanism to be brought into the Vdesired position, the link 11 isfpreferably made. in two parts and connected by an adjustin screw '13 provided with right and le t threads,engaging vrespectively the two parts pif-thelink. To enable theslide 4 tobe adjusted in a. direction 'perpendicular to thai plane'in which the slitting knives out. so

as to bring the cutting edges into the desired plane, the uides 14 which are engaged by the upwardly projecting edges of the slide, are mounted upon the of theV machine so as to ybe capable of vertical adjustment,4 as best shown in Fig. 5, adjusting screws 15v 'being providedwhich bear uponsthe upper surface of theguides, and locking screws 16 which pass through vertical slots in the frame and screw into' the guides. The insole is 'held clamped inf sition on the work support' of the mac ine during the cuttin action of the slitting knives by means oig a presser foot, indicated at 1,7, lis resser foot is mounted upon a slide l1 8 whi l reciprocates in guideways in the machine frame parallel to the guide'ways for the slide 4. A spring 19 connects the slides 43nd 18, so that during the forward p 2Q stroke of the slide 4 the slide is moved,`

' forward by the'spring 19 until the presser foot is brought into engagement with the sole, after which the sprin 19 yields and the slide 18 .and the presser oot 17 mounted thereon remain stationary during thecontinned forward movement of' the slide 4 and the slitting knives. The relative position of the presser foot and slitting knives atthe limit ofthe forward stroke of the knives is gwindicated at Fig. 4.

l In the machine illustrated in the drawings the dept-h of the cuts produced by the slitg ting knives in soles of different thicknesses is regulated byl means of the slide 18 which `carries the presser foot and which `is yieldingly connected to the knife carrying slide 4. The slide 4 is provided with an adjustable stop screw 20 mounted in a downward projection from the rear end of the slide, and the forward end of this screw is arranged to engage a pin 21 on the slide 18, after the slide 18 has been stopped by the engage. ment of the presser foot with the sole. The engagement of the screw 20 with the pin 2l are allowed to project only a predetermined distance ahead of the presser foot\ regardless of the thickness of the'sole being'operated upon. The yielding connection between the crank pin 8 and the link 11 permits the knife carryin slide to bestopped by the engagement o the screw 20 with the pin 21, the spring plunger 12 yielding as soon as the forward movement of the knife carrying slide is stopped. During the 4backward movement of the knife carrying slide the movement of the slide 18 with relation 'to the'knife carrying slide is limited by the limits the forward movement of the 'knifeI carrying slide 4 and thus the slitting knivesl andi-front plate. At its ends this casting is provided with projections 24, best shown in Figs 10, 11 and 12, which projections are received in suitably shaped recessesin the frame of the machine. The vcasting is secured in position between brackets 25 projecting downwardly from a stationary part of the machine frame, which\ brackets are forced toward each other to clamp the casting' by meansof a bolt 26 connecting the brackets, and a nut 27 having a screwleaded engagement with one end of the The position of the sole on the sole support is determined by adjustable gage pinsl 28, 29 and 30, which are arranged to engage the heel end of a sole placed in a machine. These- .gage pins project upwardly from a `slide 31 and are` adapted to move in slots formed inl the work support.. Ordinarily the heel end of the sole is engaged by the pins 28 and 30. With the smallest sizes of soles, however, the heel end of .the sole engages the -pin 29 as welll as the pin-s 28 and 30 and is thils prevented from passing backward. The slide 31 is mounted to move benea-th the sole supporting plate of the work support and is supported -upon a rod 32 which passes through a projection from the slide. i The rod 32 is supported by the front plate of the work support and lby a stationary bracket 33. To enable the slide 31 t bey adjusted for different sizes of soles itis provided upon its lower surface with a rack which is engaged by a gear 34, which gear mesheswith a pinion 35 secured to a shaft 36.- The shaft 36 is journaled in stationary brackets and is provided at one end, in a position where it is readily accessible to the operator, with a disk 37 by which it may be rotated.' This disk is provided upon its periphery, as. indicated in Fig. 5, with numerals indicating the different sizes of soles, and a stationary bracketinwhich the shaft 36 is mounted is provided with a stationary pointer 38, which cooperates with the figures on the disk 'to indicate the position of the gage pin carrying slide 31. The machine illustrated in the drawings is provided with means for marking the size numbers upon the sole, this means consisting of a number wheel 39 for marking the ,whole sizes and a number wheel 40 coper-L the work support. The numbers on the soA lWheel .39 are so arranged that when 'edisk tional sizes is 4mounted .at one side and shaft 36 areactuated to set -th gage f pm carrying slide 31 for-a givens'ize of sole,
